INVENTOR I GEGBGE F, VOIGHT, OF SAN FRANCISCO, CALIFORNIA.

VEHICLE SHOCK-ABSORBER.

Specification of Letters Patent.

Application filed November 4, L918.

To all whom ii may, concern:

itlUkOWll that I, Gannon Velour, a i 'z n or the lTnit-ed States, and resident of rancisco, into county of San Franci in, and State of California, have invented new and useful Improvements in Vehicle hoclnihsorhers, of which the following is specification, reference being had therein arconipanyin drawings.

lo a 9 My invention relates to improvements in vehicle shock ahsorhers in which oscillatory levers having one end attached to the vehicle axle and the other end attached to a portion of vehicle approximately vertically movable relatively to the axle, assist the vehicles principal leaf spring to cushion the vehicle against the. unevenness of the road over which it may travel.

in ohject of my invention is to provide oscillatory spring hanger llflVlIlQ' its outer end pirotally supported by the vehicles axle and having a section inwardly from its outer o coupled up with the outer end of the principal leaf spring of the vehicle, cooperating with a lever or levers having their outer ends pivoiallp. connected to the hanger and their inner ends niovahly supported by a portion of the vehicle movable relatively to the axle the frame or the principal leaf spring inwardly at a distancet'rom its outer end. whereby the inner end of the hanger may move upwardly and downwardly relatively to a registering section of the lovers which it over-hangs.

Another object of the invention is to provide a compression spring adapted to be con lined between the inner or free end of the hanger and a registering section of the lever or levers, whereby said inner or free end of the hanger may move upwardly and downwardly with and against the tension of said coznpre. :ion spring and whereby said compression spring may normally support, said inner end of the hanger a distance above the lever or levers.

liith the foregoing and other objects and purposes in view which will appear as the,

description proceeds. the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being i that changes in the precise em Patented llfil, liglll.

Serial No. 281,100.

bodiment of the invention as herein disclosed can be made ithin the scope of what is claimed without dparting' from the spirit of the invention.

In the drawings- Figure 1 is a rear-end elevation of a prtion of the right-hand side of a vehicle and my invention installed thereon.

Fi 2 is a top or plan view of the levers and compression spring seat, portions being in section.

Fig. 3 is a (If-a, Fig. 1.

Fig. l is a part sectional b -b, Fig. 1.

Fig. 5 is a sectional view on line c0, Fig. 1.

Fi 6 is a sectional. view in elevation, also showing a portion of the vehicles principal leaf spring in section.

Fig. 7 is a. side view of the present inventionin a somewhat modified form.

Fig. 8 is a fragmentary view of the invention in a modified form.

Fig. 9 is a view ofa portion 0i the inven tion in its modified form, on line e-e, Fig. 8.

hile I have shown my invention only as applied to the rear right-hand side of a vehicle, it is as applicable to the rear lefthand side as well as to the right-hand side, and to the front end as well to the rear end of any vehicle.

Note: Throughout the specifications and claims, the terms outer and outwardly will indicate respectivelyfarthcst; away froin-and-in a direction away frointhe median vertical plane extending longitudinally through the vehicle, and the terms inner and inwardly will indicate rcspectivelynearest to-and-in a direction toward-said plane.

Referring now to the drawings, wherein like numerals of reference indicate like parts throughout the several views,

The numeral 1 designates a vehicle road. Wheel supporting one end of an axle 2 pro vided adjacent its outer end with a rigid upwardly extending bracket {5 having a transversely extending opening through its upper end.
